To all whom it may concern:

Be it known that I, Wnmnrr C. PmRsoN, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of'Ohio, have invented certain new and useful Improvements in Compositions for Match-Heads; and I hereing absolutely no danger to the health of by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. This invention relates to new and use ful improvements in compositions for match heads.

The object of this invention primarily consists in providing a non-phosphorous composition for match-heads.

A further object of my invention is to provide a composition which can be cheaply manufactured ,ifand safely handled involvthe people employed in the manufacture and greatly minimizing the risk from egplosion or combustion" during the process of manufacture.

Afurther object of myfiinvention is to provide a composition of this character which will be practically unaffected by climatic conditions in order that the manufacture of the said composition can be carried on without interruption due to unfavorable weather conditions and also that the completed match may keep in any climate without deterioration.

With these objects in view and with the intention of securing other advantages which will hereinafter appear, my invention consistsin the composition hereinafter described -in the specification and particularly pointed out in the claims.

In carrying out my processl take a .pre-

- determined quantity of a nitrated product and heat sufficiently to dissolve the gum and other cementitious ingredients leaving the cellulose in an undissolved state. The cel- .WILLETT 0. Hanson, or cLEvnLArfi), onto.

same through, a French Buhr vgrinding mill so that the pulverized material can pass through a hundredgmesh screen. The nitrated product thus obtained I believe is nitrated cellulose.

In preparing the match-head coniposition I take a predetermined quantity of my nitrated product andaddthereto a nitrate of some metal, such as silver nitrate, copper i a tenr..leeinitiateii fi an mg agent, a binder and a filler or abrasive.

B1 mixing my ingredients I proceed 'as follows :To every twenty-four parts of the nitrated-prodfigtI 'add one part of sifver nitrate withlsufiicient Water to dissolve the nitrate and saturate theflwhole'mass which is then allowed to stand until thoroughly impregnated; The resulting product will have an acidfreaction and must preferably be neutralized and to secure theneutralization thereof'I treat the same with ammonia. The material-after neutralization is slowly dried in 'oacuo and the resulting mass, in which no" moisture should be present, is sealed in containers which will protect it from the action of light and air. The containers of course must-be perfectly dry and to insure this they must be kept in an oven for two hours at a temperature of-one hundred degrees Centigrade. It may be here remarked that the nitrated cellulose after being treated with a metallic nitrate is exceedingly light in comp rison to its bulk and by weight will' be. sufficient to dip a. very large quantity. of

a very small quantit matches. When the other materials have been prepared for mixing I take. about twenty parts of the nitrated'cellulose which splints are dipped in the usual manner this composition and a very firm head formed thereon which will ignite very all two hundred and ten parts.
